SPACIN G-MACHINE FOR CARD-CLOTHING.

Specification of Letters Patent.

Patented Oct. 8, 1918.

Application filed January 29, 1917. Serial No. 145,245.

To all whom it may concern:

Be it known that I, HERBERT MIDGLEY, a citizen of the United States, residing at lVorcester, in the county of WVorcester and State of Massachusetts, have invented a new and useful Spacing-Machine for Card- Olothing, of which the following is a speci fication.

v This invention relates to a machine for removing sections of teeth from card clothing so as to provide clear spaces thereon.

The principal objects of the invention are to provide" a simple and convenient means for removing the teeth without injuring the' remainder of the teeth or displacing them; and more specifically to provide means whereby a large number of these teeth can be forced back through the card clothing, then pulled out and entirely detached; means for holding thecard clothing during these operations and guiding it, and means for automatically releasing it from the holding means so as to permit it to be drawn through the machine.

Further objects and advantages of the invention will appear hereinafter. I

1 Reference is to be had to the accompanying drawings in which Figure 1 is a plan of a machine constructed in accordance with this invention;

Fig. 2 is a side view of the same;

Fig. 3 is an enlarged longitudinal sectional view of a portion of the machine on the line 33 of Fig. 1, that is, through the center of themachine;

Fig. 4 is a similar view on the line of Fig. 1 at the discharge end of the machine;

Figs. 5, 6 and 7 are transverse sectional views on the line 55, 6.6 and 7-7 re spectively of Fig. 1, and

- Fig. 8 is an enlarged side view of the releasing device for the holdingmeans, with parts in section and showing 1t 1n a different position from that shown in Fig. 2.

For certain purposes the teeth of card clothing are removed to provide clear spaces, and this is ordinarily accomplished, so far as I know, by hand, that is, an operative inserts a point under one or more of the U- shaped teeth and removes them by pulling them out from the back. This comparatively slow hand operation necessitates some care in getting the spaces accurate and 1ntroduces the possibility of error and eyen injury to the goods; The principal ob ect of-this invention is to do away with this hand operation and perform the same funct1on entirely by machinery.

Referring to the drawings, the invention is sllOWIl in the form of a long frame 10 having its side walls spaced apart to form guides for the card clothing A which is placed at the left-hand end of the machine, as shown in Fig. l with its teeth B down. It is threaded through the machine under a. stationary holding plate 11 and under a vertically reciprocable holding plate 12. Under this plate 12 there is a transverse shaft 13 adapted to be operated by a handle 14 secured to one end thereof and moving between stops 15 and 16 on the frame. On this shaft are two cams 17, one at each end, on which rest the ends of a support 18 for the cross plate 12. These ends 18 are held down on the cams by a pair of strong springs 19 and are adapted to be raised by the operation of the cams. The plate 12 has a plurality of screw holes for receiving a fastening screw 9 b5 which the plate is held in adjusted pos1t10ns.

Between the side guiding walls is an oscillating member 20 pivoted on a stud 21 and provided with a projecting portion 22 which rests on a cam 23 also on the shaft 13. On the top of this projection 22 is a removable plate 24 located under the space between the two plates 11 and 12. The oscillation of the shaft 13 in addition to the operation above described also raises the plate 24 for the purpose of engaging the bottoms of the teeth and forcing them up between the plates 11 and 12 into the position shown in Fig. 3. On account of the bend which occurs in the legs of the teeth they are forced up in this way only until these knees come to the underside of the card clothing, or slightly within the surface thereof.

After the parts assume the position shown at the left-hand end of Fig. 3, the handle 14 is reversed to the position shown in Fig. 2 which brings up the support 18 and the plate 12 with it.so that the latter clears the tops of the teeth I) which project above the card clothing. Then the card clothing can be drawn along by hand through the device and between adjustable top guides 25. It then passes on a platform 26 beyond the end of the member 20 and into the next part of the machine.

Here it passes between the guides with the partially extracted teeth 7) projecting upwardly from its back and comes into the position shown at the right of Fig. 3. The left-hand guide is a stationary surface of the frame 10, but at this point an adjustmoves back against a stop when out of operation. This handle obviously can be oscillated to reciprocate the {slide 30 rer- Wai'dly aihhg the ays 29 and back again. Under this slide 30 a plate 86 is hired by means of a thumb screw 37 and adjusting screws 38. This plate has a projections!) which extends up into an opening in the bottom of the slide 30. It will be seen that it can be adjusted to any desired height, and adjusted to fit slight angle to the horiziiiltal if desired. This plate 36 isprovided with a plurality of projecting plows 40 whic are spaced "apart thereon in accordancewith the width of the rowsof U-shaped teeth, so that one of these projects under each of the rows of teeth. The reciprocation of the slide 30 of course sweeps these plows alongunder the rows of teeth and as the points slant backwardly they will withdraw the teeth from the card clothing. The teeth than then be removed byany desired means. Altheugh I have shown 'no 'ineans for reiiioving them I have found at "electiomagnet convenieht device for accomplishing this result.

The pemiio f-eXtra'cting the teeth being completed; the handle 34 is drawn back against the stud 35. In other wordspwhen 'not operated it is always brought back to the position shown in Figs. 1 2611612. Thebr-ing ing of the slide 30 back to this position has another function because theend bf the rack 31 engages an upwardly extending projection 41 him a wedge-shaped'slide42 "which is heating p essed by a s ringas forwardly up an "inclinedplane 454-. This wedge-shaped slide 42 has preferably a soft surface formed of a strip'of leather or rubber 4:5 and is designed when forced upwardly by the spring into the position shown in Fig. to engage the under ends of the teeth of the card clothing and grip it into engagement with the top plate 47 which o'ver's this pm of the device. But when the rack moves back and engages the projection 41 the wedge-shaped slide 42. is forced back positively, and consequently the teeth released, so that the Operative can pull the card clothing through. The motions of the "slide 2 1 are limited by a is 46 which eitends through a slot '47 in the sia f the iraihe; this shit bein arra'ngedparallel "with the plane etet. The movement of the card clothing through the machine can be accomplished automatically, but is preferably accomplished by hand so no means is shown herein for doing it.

The operation of the device is very simple. The card clothing is threaded through the lefthand end of the machine under the plates 11 and 12 when the latter is in the position shown in Figs. 1 and 2, and brought to the proper position, when the handle 14 is jswuiifg over to the position shown in Fig. 3. This lowers-the plate 12 ihto the position shown in 3. and raises the plate 24f's'o as to TMCeItli' wires up through the card c'othing", as shown in that figure, leaving their U-shaped portions projecting t an the bac'k. During this s paratism it is tobe observed that the plate 121?. iota-ted down the surface cf the hard Clothing, being held there by thespiihgs 19. The

handle 14 is then reversed back to the posi tion shew-h in Figs. 1 and 2agaih s't thest'op 15 "which raises this Plate 12 and lev rs the plate 24, it is at this tini'e that 'the'hperativ'e pal-1s it throu h for another space. This can haematite by' measurement pr by the eye at the o erative, mhe plate 12 can befma'de just wide enough 'Sdftll at the upwardl projecting teeth c h'be thong-ht back against it to s'ec'fiife the proper spacihg. As soon as 'enough'of these op'ei'ation s'have been performed to bring the first 'p-Mjecti'hg teeth 7) into the vicinity theektracting plows 40 the hiihdle 8 f TS av foi ward to 't'lie dotted pesit'ioh in Fig; 2, and then back, to its rmal pesitieiis'hoivn in full lines. This V the teeth extracts them. entirely the card clbthing. this opeiation the card "clothing is held a gai-nst metion backwardly by the wed'ge shaped plate 452 coining into the position shown 'in' fFig'. 4. The backward motion of the haii'diefittheii releases thefard clcthing, as previously "de- "scribed, and the ashram-i e tan then pull it through.
